For legacy licenses, System Coupling requires an &#8220;ANSYS Structural&#8221; or higher license and any CFX\/CFD-Flo license for the duration of the calculation.  For current licenses, System Coupling requires an &#8220;ANSYS Mechanical Enterprise\u201d license and any Fluent\/CFX\/CFD-Flo license for the duration of the calculation. The most cost effective way to conduct a 2-way FSI analysis is to use the \u201cANSYS Mechanical CFD\u201d, which allows you to perform the 2-way analysis using this single license. When not performing an FSI analysis, only one solver can be run at a time using this license.  There is a defect in version 18.0 and earlier whereby when using multiple licenses for a system coupling analysis (e.g. Mechanical Enterprise + Multiphysics), the license preferences for license sharing must be set to allow for license sharing. Otherwise, CFX-Pre may call for the license before Meshing has released it, resulting in the following error:  &#8220;Error opening CFX Setup case file. License check out failed.&#8221;  This defect has been fixed in version 18.1.<\/p>\n","protected":false},"template":"","class_list":["post-171359","topic","type-topic","status-publish","hentry","topic-tag-18-1","topic-tag-fluid-dynamics","topic-tag-general","topic-tag-system-coupling"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["2\/6\/2023 20:20"],"_bbp_forum_id":["27796"],"_bbp_author_ip":["209.182.204.162"],"_btv_view_count":["461"],"siebel_km_number":["2049223"],"product_version":["18.1"],"km_published_date":["2017-04-27T00:00:00.000Z"],"family":["Fluid Dynamics"],"application_name":["System Coupling"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/171359","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/171359\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=171359"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
